Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Ruby-throated Hummingbird
Deciduous and mixed forests, woodland edges, gardens, and parks with flowering plants. Migrates across the Gulf of Mexico.
Song & Call Comparison
African Penguin
A loud, donkey-like braying 'waaah-waaah' — hence its nickname 'jackass penguin'. Also gives softer grunts and contact calls at the colony. Highly vocal on breeding beaches.
Ruby-throated Hummingbird
Soft, high-pitched chattering and twittering 'chee-dit'. Also produces a thin 'tik' call in flight. Wing beats create an audible high-pitched humming buzz during hovering.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Ruby-throated Hummingbird
Eastern North America from southern Canada to the Gulf Coast. Winters in Central America and southern Mexico.

Black upperparts and white underparts with a distinctive black horseshoe-shaped band across the breast. Pink patches of bare skin above the eyes help with thermoregulation.
Sturdy, pointed, black bill with a grey band near the tip
Ruby-throated Hummingbird
Metallic green upperparts and greyish-white underparts. Males have a brilliant iridescent ruby-red gorget that appears black in poor light. Females lack the gorget.
Long, straight, thin black bill adapted for probing flowers
About These Birds

南アフリカ西部沿岸とその島嶼に生息するペンギン（体長60〜70cm）。黒い背中と白い腹に黒い縦縞、眼上部のピンクの皮膚が特徴的。Spheniscus demersus（アフリカペンギン）はロバのような「ブレイヤー」という鳴き声から「ジャッカスペンギン」とも呼ばれる。過去1世紀で個体数が97%以上減少し、絶滅危惧種に指定されている。Spheniscidae科。
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
